JAVA / J2EE / MAIN FRAME

  • JAVA

    Java is a general-purpose computer-programming language that is concurrent, class-based, object-oriented,[15] and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA),[16] meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.

    Java is among the most popular programming languages out there, thanks to its versatility and compatibility. Java is used for software development, mobile applications, and large systems development.

  • J2EE

    J2EE is a platform-independent, Java-centric environment from Sun for developing, building and deploying Web-based enterprise applications online. The J2EE platform consists of a set of services, APIs, and protocols that provide the functionality for developing multi-tiered, Web-based applications.

    J2EE technologies are Java Servlets, Java Server Pages (JSP), Enterprise JavaBeans (EJB) and the Java Message Service (JMS). Following on from this, we'll move on to take a look at J2EE from an architecture and design perspective, covering topics like best practices and design patterns.

  • MAINFRAME

    A mainframe is a high-performance computer used for large-scale computing purposes that require greater availability and security than a smaller-scale machine can offer. Mainframes have been associated with centralized rather than distributed computing, although that distinction is blurring as smaller computers become more powerful and mainframes become more multi-purpose.

Java is one of the most popular programming languages used to create Web applications and platforms. It was designed for flexibility, allowing developers to write code that would run on any machine, regardless of architecture or platform.

Python is used in many application domains such as Web and Internet Development. Python is widely used in scientific and numeric computing.

J2EE is comprised of many APIs that can be used to build enterprise applications. For completeness, however, the full list of technologies that make up J2EE is as follows: Java Servlets. JavaServer Pages (JSP), Enterprise JavaBeans (EJB)

The mainframe offers many advantages for cloud computing. Mainframes provide the ideal platform for big data analytics, data warehouses, production processing, and web applications while supporting millions of users with superior performance.
